Is A in a circle a current source?
Ok. So total power provided to the circuit is P=100*10=1000 W.Current source? No. A(for amps) is simply measuring the current on that circuit.
V = 100
I(t) = 10A
R1 = resistor using 500w
R2 = resistor using 100w (in parallel with R3)
R3 = resistor using ?w (in parallel with R2)
Need ohms value of R3
You know the current through R1, it is 10 A.Isn't there a voltage drop after R1? Trying to calculate the ohms value of R1 from watts. Is the value of R1 10 ohms? 100V divided by 10A = 10 ohms. But the voltage drop....stuck on that.
R1 is 5 Ohm.Ok, so R1 = 5Ω and R2 = 1Ω Am I correct?
R1 is 5 Ohm.
R2 is not 1 Ohm because before you get to R2 the current is split into two. So some part of 10 A goes through R2, another part of 10 A goes through R3.
The bottom line is that we don't give a damn about resistance and current through R2. The only thing we want from R2 is the voltage across R2. The voltage across R2 is 100 V minus Voltage across R1. Which also means that we don't give a damn about resistance of R1. So why the eF are you wasting your time on figuring out that R1 is 5 Ohm?
Simple. I told you how to find Power at R3. I told you how to find Voltage at R3. All you have to do now is to solve for resistance of R3.Ok, so if R1 is 500w, and the current is 10a, (V=W/I) then we're looking at 50v at R1.
Now, since the current is divided into 2 before R2 and R3, and R2 is 100w consumption, how do I figure out the resistance of R3?
